Pinyin transliteration of Mandarin廣西／广西 (Guǎngxī). 廣／广 (guǎng) itself means "expanse", and has been associated with the region since the creation of Guang Prefecture in 226 AD. "Guangxi" and neighbouring Guangdong literally mean "Guang West" and "Guang East". Together, Guangdong and Guangxi are called the "Two Guangs" (兩廣／两广 (Liǎngguǎng) Liǎngguǎng).
